                 StreamingMarshaller m)
          throws CacheLoaderException

Description copied from interface: CacheLoader

Used to initialize a cache loader. Typically invoked by the CacheLoaderManager when setting up cache loaders.

Specified by:

init in interface CacheLoader

Parameters:

config - the cache loader configuration bean

cache - cache associated with this cache loader. Implementations may use this to determine cache name when selecting where refer to state in storage, for example, a different database table name.

m - marshaller to use when loading state from a stream, if supported by the implementation.

Throws:

CacheLoaderException
